Garbage cans
Even the sturdiest trash bag is prone to leave little bits of food and garbage lingering in your trashcan that can fester and leave unpleasant smells even after you take out the trash.
Small indoor trash cans can sometimes fit in your dishwasher for a thorough clean.
For large indoor or outdoor garbage bins, take them outside, add some dish soap, scrub them out and spray them down with a hose.
